摘要
基于单向函数和有限域上离散对数问题提出一种动态多秘密分享方案.本方案构成简便,容易检测秘密分享成员的欺诈行为,能够解决秘密更新与复用的问题,且可以很方便地增加和删除系统成员.整个方案安全性高,涉及计算复杂度小,需保存信息少,因而效率高且实用。
Based on the computational difficulty of computing discrete logarithms, a dynamic multiple secrets sharing scheme is proposed. It has simple structure, can easily identify the cheaters of all shareholders and can effectively solve the renewal and reuse problems and accept a new participant or fire a participant freely. The scheme is characterized by high security, small computational complexity, and small amount of information that should be kept. The scheme is relatively efficient.
